A patent, No. 510,631, was granted escape of steam.

In my present device I prosons hereinafterexplained. This controlling- 9o 40 vide, among other things, means whereby a valve E E is operated by a valve-operating time mechanism for regulating the predeter mechanism F F, which operates to open it, mined period during which the oxidizing vato hold it open during a predetermined interpor or gas is injected is placed at a'distance val, and then to closeit. v from the boilersay in the main office of a At a point remote from the boile r-room, if 5 5 factory, or more orless remote from the boilerso desired, is placed a clock device G,Fig. room-in order thatsaid predetermined inter- 1, and at any suitable point is placed a source val may not be interfered with or changed by of electrical energy II. A second battery or the fireman. I also provide. means whereby source of electrical energyIl is also provided said interval may be changed or regulated acfor operating the clock G. [00 5o cording to the character of the fuel used orac- The magneto B, the valve-operatin g mechcording to the other circumstances of the case. anism F, and the clock G are connected by a system of wiring, and the wires of this system are numbered, as shown in Fig. 1, 1 2 3 4 5. The magneto B, the valve-operating mechanism F, and clock G are connected by another system of wiring, the wires of which are lettered a Z) c d e, as shown in the same figure.

The magnetos B B are of any ordinary construction adapted to produce an electrical impulse of proper energy whenever the shaft or connecting-rod B B is turned to a proper degree. These magnetos, therefore, need no further explanation. From each magneto extends a pair of conducting-wires, as hereinafter explained. An equivalent for any of these magnetos is found in any device or arrangement capable of imparting a suitable electrical impulse to the electromagnets hereinafter described.

The clock G is any ordinary clock-movement, although I prefer to use for the same an electrical clock operated or wound by the battery II and connected thereto by the wires Tothisordinaryclock-movement,which needs no further explanation, I add a shaft G. (See Figs. 6 to 10, inclusive.) This shaft is geared to the clockwork, as by means of the gear-wheel G and pinion G so as to have a slow movement of revolution. To the clockframe isattached asupporting-frame g, which bears one or more electromagnets g each electromagnet being related to one of the wiring systems and to one of the steaminjection pipes D D. In the present case I have shown two such pipes D D and two ordinary electromagnets, each provided with an armature. Each electromagnet is provided with a swinging armature g g. These armatures are pivoted, as at 9 to the supporting-frame g, and are so balanced as normally and when the electromagnet is not energized to restagainst a suit-able stop 9, attached to the supporting-frame g.

On the shaft G there is placed a contactpiece 2", relating to each eleetromagnet. This contact-piece or arm .2 (see Figs. 8, 9. and 10) is clamped upon the shaft G, so that, notwithstanding. the revolution of the shaft in the direction shown by the arrows in Figs. 7, 9, and 10, the arm may be moved backward or in a direction contrary to the arrow, thus slipping upon the shaft in its backward movement. This movement is given to the arm whenever an electrical impulse passes through an eleetromagnet, raising its armature from the stop g whereby the end of the armature in rising strikes the end of the arm .2 and lifts it into the position shown in Fig. 9. If now the armature 9 falls back against the stop 9, as shown in full lines in Fig. 10, and the revolution of the shaft G continues, the shaft carries with it the arm 2 (by reason of the friction of the bearing of the arm upon the shaft) toward the position shown in dotted lines in Fig. 10. To the frame 9 and underneath each arm .2 or 2 is fastened an independent adjustable contaet-point 9 y the contact-points beinginsulated from the frame 9 by the insulating-block g. Each contactpoint is in the drawings a screw which may be raised or lowered, and thus the period of injection in to the fire-space may be varied for any fire, and the different fires may have injections of different periods. lVhen the armature 9 (see Figs. 9 and 10) rises to its extreme upper position, (shown in Fig. 9,) the arm is raised to its extreme upper position, and this upper position is a fixed position, which cannot be varied. The stop-block g may be raised and lowered, so as to determine the lowest operative position of the armature g", and the arm z may turn these limits namely, the extreme upper position shown in Fig. 9 and the extreme lower position to which it may move before striking the armature g in its lowest position. Between these limits the contact-point or screw g -may determine the extent of movement of the arm .2 and thereby determine, as hereinafter shown, the time during which the injection of the steam shall occur into the boiler. \Vhen the arm z is raised to the extreme upper position of Fig. 0 and the armature 1 drops away from it, the shaft G begins to move the arm in the direction of the arrows assoon as the arm is released. The slow movement of the shaft continues until the arm strikes the contact-point g whereupon it is held against further movement, and the shaft G continues to revolve within the bearing of the arm until the armature is again raised.

Each valve-operating mechanism F or F consists of an electrical motor, which is normally stationary and is only operated when a current from the battery His permitted to pass through it. In each of these mechanisms I place a rheostat F (see Fig. 2,) whereby the action of the motor is retarded to the desired degree. In combination with the n10- tor I provide the following devices for operating the valve E, which are shown in Figs. 2, 3, and 4. The motor F Fig. 2, is of any suitable type and operates a shaft F bearinga disk F. This disk has a series of notches f on its periphery, for which notches there may be substituted as equivalents pieces of insulating material. Upon the disk F are also two studsf f To suitable insulatingblocks in the regulator and in suitable relation to the disk F are fixed 'a pair of contact-springs ff, the springs being adapted for contact with the studs f f and the spring f being adapted for contact with the periphcry of the disk F", but being so adjusted, as shown in Figs. 2 and 4, that when in the revolution of the disk the notches come opposite to said springf the contact between the disk and spring is broken. The studs f and f are arranged in adiameterof the wheel and the notches or insulating-spots f are arranged in pairs, one on each side of the studs f f and about thirty degrees in are from said studs, measured upon the periphery of the disk F Each valve E is connected to the regulator by a stem e, which is pivoted at e to a lever f. This lever is pivoted at one end f to one end of a link f the other end of which is pivoted to the case of the regulator. The pivotal point e of the rod 6 is intermediate the pivotal point f at one end of the lever f and the other end of such lever. A suitable guide e serves to prevent sidewise movement of the lever, and, if desired, an adjustable spring 6 upon a suitable post serves to normally tend to raise the lever f? and open the valve E.

Each valve-operating mechanism F F bears an electromagnet F adapted to actuate an armature F which latter is pivoted to the regulator-frame and is normally drawn away from the magnet either by gravity or by a spring 1;, as shown in Fig. 2. Near to the disk F is pivoted, as at 2', a swinging lever I, having three branches t" 11 i The branch 2" is adapted to be engaged by either of the studs f orf in the course of their revolution and to be depressed by said stud, so that the arm "6 on the other side of the pivotal point i shall rise and engage the lower side of the lever f and raise the same to open the valve E. Upon the same pivot 'i is hung a gravitylatch 6 provided with a notch or ledge i in position to engage the armature F when the armature is raised and to hold the same in its elevated position. The latch 11 is heavily weighted at its lower end and is provided with an adjusting-screw '5 which engages the arm i before mentioned, and so tends to return the lever I to its normal position ready tobe engaged by either of the studsf or f I now proceed to describe the circuits by means of which my device is operated. It may first be stated that the clock or motor G runs continuously and that the motor or clock-movement of each regulator F or F runs intermittently.

When a fire-door A'orA is opened, the connecting-rod B or B of one of the magnetos B or B is turned, operating the magneto and creating a current which passes through the wires 4((1) and 5, (6,) connected to the magneto. The current in the wire 5 (e) passes to the magnets g g in the clock G, energizing these magnets, which raises the armature g or g and lifts the arm 2 or .z away from the contact-piece g or 9 as hereinbefore explained. The same currentpasses through the wire 5 (e) to the valve-operatin g mechanism F into the magnet F energizing the same and raising the armature F so that the latch 2' engages said armature and holds it in the extreme upper position. The tail of this armature F makes contact with the spring or plate y, and a current from the battery H passes through the armature F through its supportingbracket into the motor-frame, through the magnets of the motor F and out through the wire 2 The wire 2 or b is connected to the magnets of the motor, but is insulated from i the clock or motor frame and from the action of the regulator. Thus the action of the ma neto is to disconnect the contact between the arm 2 or a and its corresponding contactpiece 9 or g in the clock G, but to connect the wires 2 (b) and 3 in the regulator to start the motor therein. This causes the disk F to revolve, and as soon as this revolution has continued fora short time the spring f comes in contact with the periphery of the disk F and a current from the wire 3 passes into the disk, into shaft F thence into the frame of the motor F through the motor, and out through the wire 2, continuing the connection of the battery H therewith.

The first movement of the disk F from the normal position of rest shown in Fig. 2 moves the lever I and the latch 45 to disconnect the latch from the armature F whereby the ar-.

circuit just mentioned through said contactpiece, but continuing the circuit through the spring f and through the wire 2. By the time that the spring f breaks contact with the periphery of the disk F the arm f has been lifted by the lever I and the valve E is opened, but now contact is made by the spring f with the stud f and a current may pass through the wire I, spring f, stud f disk F shaft F through the motor F and out through the wire 2 to the battery H, thence to the clockframe through. the wire Z to the shaft G, through the arm 2, and to the contact-piece g as soon as the arm and contact-piece are brought in contact by the revolution of the shaft G; but as no current can now pass through the motor F until this contact is made the motor stops and the valve is held open with the parts in the position shown in Fig. 4. This contact occurs at the end of a predetermined periodsay five minutes. The

circuit just mentioned is established and the disk F5 again begins to revolve. When the latch 11 is released from the armature F by the passage of the stud f from the arm 2', the tail of the armature F makes contact with the spring-stop to, which simply acts to prevent the armature from being thrown too far by the spring 1* from the magnets F As soon as the stud f has passed from contact with the spring f the current through the wires 1, Z, and 2 is broken anda current is reestablished through the motor by the wires 3 and 2 by reason of the contact of the spring f with the periphery of the disk. The motor F and the disk 13 continue to revolve after the contact is made by the arm 2 with its contact-point 9 The stud f depresses the lever f closes the valve E, and when the valve is closed the springs f and f have the position relative' to the disk F shown in Fig. 2, whereupon, all circuits from the battery H being broken, the motor-stops. It will be noticed that for each complete operation the disk F makes a half-revolution. The period of time during which the lever f is kept in its raised position, whereby the valve E is kept open, depends upon rate of revolution of the shaft G and the variable distance of the arm from its contact-point. The rate of revolution of the disk F determines the length of time which shall be occupied in opening and in closing the valve E, and this rate may be changed by means of the rheostat F whose resistance-coils are placed in the circuit passing through the contactspring f.

The modification shown in Fig. 11 contains the same elements as the prior device, but with a different system of wiring and slightlydifierent method of operation. Vhenthe magneto B is operated by opening the furnacedoor, an impulse is sent through the wires 4 5 to the electromagnet F of the valve-operating device, the armature F is raised, the disk F begins to revolve, the lever I is tilted until it reaches its extreme position, and the latch i is then brought into contact with the contact-point f This contact completes a circuit through the wires 6 7 3, spring f, disk F lever I, and latch i through the battery H, and through the magnets g of the clock G, raising the armature g and disconnecting the contact 2 from the contact-pin 9 The revolution of the clock G returns the arm 2 to make contact with the pin 9 In all other respects the devices shown in Fig. 11 and those shown in the other figures are the same.

My invention involves the features that the operation of the valve and the consequent blast are independent of the closing of the furnace-door; that the valve is operated by positive mechanism, throwing it wide open ata predetermined rate of movement, holding it wide open during a predetermined interval, and then closing it at said predetermined rate, and that said rate and said interval may be varied and adjusted to the character of the fuel, the pressure and temperature of the steam, and other circumstances of the particular case. After the furnace-door is opened the remaining operations of my device occur automatically.

I do not limit the scope of my invention or the claims hereinafter set forth to the exact construction shown herein; but I intend that said claims shall be capable of such an application of the doctrine of equivalents as Will retain to me the full benefit of the invention which I have made in view of the state of the art.
